Usage

Case 1 (default behavior):

Output to a standalone css file and a minified css file. The output destination is the same dir of 'bundle.write(options)' options.file.

import { rollup } from 'rollup';
import css from 'rollup-plugin-css-porter';

rollup({
  input: 'main.js',
  plugins: [ css() ]
}).then(bundle => {
  bundle.write({
    format: 'es',
    file: 'bundle.js'
  });
});

Case 2:

Output to a standalone css file without minified css file. The output destination is the same dir of 'bundle.write(options)' options.file.

import { rollup } from 'rollup';
import css from 'rollup-plugin-css-porter';

rollup({
  input: 'main.js',
  plugins: [ css({minified: false}) ]
}).then(bundle => {
  bundle.write({
    format: 'es',
    file: 'bundle.js'
  });
});

Case 3:

Output to a specific path if config the plugin options.dest.

import { rollup } from 'rollup';
import css from 'rollup-plugin-css-porter';

rollup({
  input: 'main.js',
  plugins: [ css({dest: 'path-to-my-dir/bundle.css'}) ]
}).then(bundle => {
  bundle.write({
    format: 'es',
    file: 'bundle.js'
  });
});

Case 4:

Output to a standalone css file with only minified css file. The output destination is the same dir of 'bundle.write(options)' options.file.

import { rollup } from 'rollup';
import css from 'rollup-plugin-css-porter';

rollup({
  input: 'main.js',
  plugins: [ css({raw: false}) ]
}).then(bundle => {
  bundle.write({
    format: 'es',
    file: 'bundle.js'
  });
});

Case 5:

Custom output filenames by config a string value for plugin raw and minified option :

import { rollup } from 'rollup';
import css from 'rollup-plugin-css-porter';

rollup({
  input: 'main.js',
  plugins: [ css({
    raw: 'custom.css',
    minified: 'custom.min.css',
  }) ]
}).then(bundle => {
  bundle.write({
    format: 'es',
    file: 'bundle.js'
  });
});

Or:

css({
  raw: 'custom.css',
  minified: false,
})

Or:

css({
  raw: false,
  minified: 'custom.min.css',
})
